Import stacks into AWS CloudFormation StackSets - AWS CloudFormation

Import stacks into AWS CloudFormation StackSets

A stack import operation can import existing stacks into new or existing StackSets, so that you can migrate existing stacks to a StackSet in one operation.

For self-managed StackSets, the import operation can import stacks in the administrator account or in different target accounts and AWS Regions. For service-managed StackSets, the import operation can import any stack in the same AWS Organizations as the management account.

The following are considerations and limitations when importing stacks into StackSets:

  • The import operation can import up to 10 stacks using inline stack IDs or up to 200 stacks using an Amazon S3 object.

  • The NoEcho property is not supported. Stacks that contain NoEcho won't be imported into new StackSets through StackSet import.

  • Stacks can only belong to one StackSet.

  • You can implement stack tags to the StackSet by specifying tags explicitly as parameters in the stack import operation.

  • A stack's custom parameter overrides aren't affected during the import operation.

  • Parameters of imported stack instances can't be updated using the Edit StackSet details option. You must use the Override StackSet parameters. For more information on overriding parameters, see Override parameters on stacks.

  • The StackSets quotas and stack instances apply when importing stacks. For more information about quotas, see Understand CloudFormation quotas.
